* uart(4): Honor hardware state of NS8250-class for tsw_busyMarius Strobl2024-01-189-8/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 9750d9e5, I brought the equivalent of the TS_BUSY flag back in a mostly hardware-agnostic way in order to fix tty_drain() and, thus, TIOCDRAIN for UARTs with TX FIFOs. This proved to be sufficient for fixing the regression reported. So in light of the release cycle of FreeBSD 10.3, I decided that this change was be good enough for the time being and opted to go with the smallest possible yet generic (for all UARTs driven by uart(4)) solution addressing the problem at hand. However, at least for the NS8250-class the above isn't a complete fix as these UARTs only trigger an interrupt when the TX FIFO became empty. At this point, there still can be an outstanding character left in the transmit shift register as indicated via the LSR. Thus, this change adds the 3rd (besides the tty(4) and generic uart(4) bits) part I had in my tree ever since, adding a uart_txbusy method to be queried in addition for tsw_busy and hooking it up as appropriate for the NS8250-class. As it turns out, the exact equivalent of this 3rd part later on was implemented for uftdi(4) in 9ad221a5. While at it, explain the rational behind the deliberately missing locking in uart_tty_busy() (also applying to the generic sc_txbusy testing already present).

* igb(4): Remove disconnected SYSCTLMarius Strobl2024-01-182-11/+0
| | | | | | | | | | | The global hw.igb.rx_process_limit knob never was adhered to by the in-tree version of this driver but similar functionality is available via the device-specific dev.igb.N.iflib.rx_budget. While at it, remove the - besides initialization of tx_process_limit - unused {r,t}x_process_limit members. (cherry picked from commit f221d35be7a5749e2a1246c81adc9c03c1dc545c)

* kern linker: Do not retry loading modules on EEXISTZhenlei Huang2024-01-151-1/+4
| | | | | | | | | | | | | | | | LINKER_LOAD_FILE() calls linker_load_dependencies() which will return EEXIST in case the module to be loaded has already been compiled into the kernel. Since the format of the module is now recognized then there is no need to retry loading with a different linker, otherwise the userland will get misleading error number ENOEXEC.

* ena: Add sysctl support for spreading IRQsOsama Abboud2024-01-143-22/+263
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows spreading IO IRQs over different CPUs through sysctl. Two sysctl nodes are introduced: 1- base_cpu: servers as the first CPU to which the first IO IRQ will be bound. 2- cpu_stride: sets the distance between every two CPUs to which every two consecutive IO IRQs are bound. For example for doing the following IO IRQs / CPU binding: IRQ idx | CPU ---------------- 1 | 0 2 | 2 3 | 4 4 | 6 Run the following commands: sysctl dev.ena.<device index>.irq_affinity.base_cpu=0 sysctl dev.ena.<device_index>.irq_affinity.cpu_stride=2 Also introduced rss_enabled field, which is intended to replace '#ifdef RSS' in multiple places, in order to prevent code duplication. We want to bind interrupts to CPUs in case of rss set OR in case the newly defined sysctl paremeter is set. This requires to remove a couple of '#ifdef RSS' as well in the structs, since we'll be using the relevant parameters in the CPU binding code.
